This section will provide you with a roadmap to demonstrate how to build an applica-
tion from scratch using Advantech DAQNavi Device Driver with your favorite devel-
opment tools such as Visual Studio.Net, Visual C++, Visual Basic, Delphi and C++
Builder. The step-by-step instructions on how to build your own applications using
each development tool will be given in the Device Drivers Manual. Moreover, a rich
set of example source code is also given for your reference.
1.6.1 Programming Tools
Programmers can develop application programs with their favorite development
tools:
Visual Studio.Net
Visual C++ and Visual Basic
Delphi
C++ Builder
For instructions on how to begin programming works in each development tool,
Advantech offers a Tutorial Chapter in the DAQNavi SDK Manual for your reference.
Refer to the corresponding sections in this chapter on the DAQNavi SDK Manual to
begin your programming efforts. You can also look at the example source code pro-
vided for each programming tool, since they can get you very well oriented.
The DAQNavi SDK Manual can be found on the companion DVD-ROM. Alternatively,
if you have already installed the Device Drivers on your system, The DAQNavi SDK
Manual can be readily accessed through the Start button:

Chapter 1 Introduction
1.6.2 Programming with DAQNavi Device Drivers Function Library
Advantech DAQNavi Device Drivers offer a rich function library that can be utilized in
various application programs. This function library consists of numerous APIs that
support many development tools, such as Visual Studio.Net, Visual C++, Visual
Basic, Delphi and C++ Builder.
According to their specific functions or services, APIs can be categorized into several
function groups:
Analog Input Function Group
Digital Input/Output Function Group
Event Function Group
For the usage and parameters of each function, please refer to the Using DAQNavi
SDK chapter in the DAQNavi SDK Manual.
1.6.3 Troubleshooting Device Drivers Error
Driver functions will return a status code when they are called to perform a certain
task for the application. When a function returns a code that is not zero, it means the
function has failed to perform its designated function. See Device Driver Manual for
detailed information about Error Code.

2.1 Unpacking
After receiving your PCIE-1840 package, inspect its contents first.
The package should contain the following items:
PCIE-1840 card
Auto-Calibration Board
Companion CD-ROM (DLL driver included)
Startup Manual
The PCIE-1840 cards harbors certain electronic components vulnerable to electro-
static discharge (ESD). ESD could easily damage the integrated circuits and certain
components if preventive measures are not carefully paid attention to.
Before removing the card from the antistatic plastic bag, you should take following
precautions to prevent ESD damage:
Touch a metal part of your computer chassis with your hand to discharge static
electricity accumulated on your body. Or use a grounding strap.
Touch the anti-static bag to a metal part of your computer chassis before open-
ing the bag.
Hold the card only by the metal bracket when removing it from the bag.
After taking out the card, you should first inspect the card for any possible signs of
external damage (loose or damaged components, etc.). If the card is visibly dam-
aged, please notify our service department or the local sales representative immedi-
ately. Avoid installing a damaged card into your system. Also, pay extra caution to the
following aspects to ensure proper installation:
Avoid physical contact with materials that could hold static electricity such as
plastic, vinyl and Styrofoam.
Whenever you handle the card, grasp it only by its edges. DO NOT TOUCH the
exposed metal pins of the connector or the electronic components.
2.2 Driver Installation
We recommend you install the driver before you install the PCIE-1840 card into your
system, since this will guarantee a smooth installation process.
The Advantech DAQNavi Device Drivers Setup program for the PCIE-1840 card is
included in the companion DVD-ROM that is shipped with your DA&C card package.
Please follow the steps below to install the driver software:
1. Insert the companion DVD-ROM into your DVD-ROM drive.
2. The Setup program will be launched automatically if you have the auto play
function enabled on your system. When the Setup Program is launched, you
can follow the installation guide to correctly install the driver step by step.
Note! Keep the anti-static bag for future use. You may need the original bag to
store the card if you have to remove the card from the PC or transport it
elsewhere.

edges and carefully align it with the slot. Insert the card firmly into place. Use of
excessive force must be avoided, otherwise the card might be damaged.
6. Fasten the bracket of the PCI card on the back panel rail of the computer with
screws.
7. Plug in the power cord and turn on the computer.
2.3 Device Setup & Configuration
The Advantech Navigator program is a utility that allows you to set up, configure and
test your device, and later stores your settings on the system registry. These settings
will be used when you call the APIs of Advantech Device Drivers.
Setting Up the Device
1. To install the I/O device for your card, you must first run the Advantech Naviga-
tor program (by accessing Start/Programs/Advantech Automation/DAQNavi/
Advantech Navigator).
2. You can then view the device(s) already installed on your system (if any) on the
Installed Devices list box. If the software and hardware installation are com-
pleted, you will see PCIE-1840 card in the Installed Devices list.

information about how to connect
input and output signals to the
PCIE-1840 cards via the I/O con-
nector.

PCIE-1840 User Manual 14
3.1 Overview
Maintaining signal connections is one of the most important factors in ensuring that
your application system is sending and receiving data correctly. A good signal con-
nection can avoid unnecessary and costly damage to your PC and other hardware
devices. This chapter provides useful information about how to connect input and
output signals to the PCIE-1840 cards via the I/O connector.
3.2 Jumper Settings
Setting the BoardID Switch (SW1)
The PCIE-1840 has a built-in DIP switch (SW1), which is used to define each card's
board ID. You can determine the board ID on the register as shown in Table 3.1.
When there are multiple cards on the same chassis, this board ID setting function is
useful for identifying each card's device number through board ID. We set the PCIE-
1840 board ID as 0 at the factory. If you need to adjust it to other board ID, set the
SW1 by referring to DIP switch setting.
